Product Description

AL2O3 36% 40% 42% Clay brick for hot blast stove/High temperature low creep/High thermal shock resistance



Category of Refractory Brick/Fire Brick:

Clay bricks are made of clay clinker as aggregate and refractory clay (soft clay or semi-soft clay) as binder, and the content of AL2O3 is 30%-48%.It is a kind of refractory product with wide application and huge output.Clay products are acidic refractory products, and the acidity increases with the increase of SiO2 content.It has a certain resistance to acid slag erosion, but the resistance to alkaline slag erosion is poor, so clay products should be used as the lining of acid kiln;Also used in blast furnace, hot air furnace, glass kiln, carbon roasting furnace and other high temperature kiln.


Production process:
The production process of Clay bricks can be divided into as following process:
Raw material mixing, molding, sintering, selection, packing, delivery.
1) Generally, Clay bricks was molded by dry pressing.
2) By means of mixing the material uniformity in proportion and ageing mixture some time. Then, pour some powders into the mold and dry pressing.
3) After dry pressing, the adobe needs to be pushed in the drying kiln to stove or stay in the air to dry. This progress will need about 3-5 days.
4) After this progress, then push the adobe into the tunnel furnace or shuttle kiln to burn around 1300C. This progress will be need about 5-7 days.
5) After burning, the finished Clay bricks will be packed on pallet.

Resistance to High temperature, Resistance to erosion, resistance to abrasion;
Excellent compression strength;
Resistance to acid and alkali;
Excellent heat stability.

Clay bricks used in hot air furnace are required to have good thermal shock resistance, high softening temperature under load and small creep, mainly used in regenerator and partition of hot air furnace.
